METALL'IC RAILROAD-TIE,

SPECIFICATION forming part of Letters Patent No. 270,637, dated January 16, 1883.

Application Filed August 31, 1885.. (No model.)

To all whom it may concern Be it known that I, JOSEPH CLARK, of Brooklyn, in the countyl of Kings vand State of- New York, have invented certain new and useful Improvementsin Metallic Railroad-Ties, of which the following is a specification.

This invention has reference to certain iinprovements in the metallic railroad-ties for which Letters Patenthave been granted to me heretofore under date ot' June 6, 1882, and numbered 259,095, said improvements being designed with a view to ada-pt the tie in a higher degree to practical requirements and of preventing accidents in case ot derailment of the cars; and the invention consists ot' a base plaie having seats or sockets for the arched bearing-plates and chairs for the rails cast integral therewith, and of arched bearing-plates having top recesses for the rails and clamps for attaching the rails tothe chairs, the top recesses for the base of the rails being arranged somewhat to one side of the center. line ot' the arched plate, so that by reversing the position ofthe same small inequalities or inaccuracies in the shape of the rails may be compensated. Thebearing-platesareprovided with beveled or inclined portions that extend at both sides ofthe central recess toward the ends of the plates, the inclined portions serving to keep derailed cars close to the rails.

In the accompanying drawings, Figure l represents a plan view of my improved metallic railroad-tie. Fig. 2 is a vertical longitudinal section through a part ot' the tie on line x m, Fig. l; and Fig. 3 is a detail top View of the arched bearing-plate of the rail.

Similar letters of reference indicate corresponding parts.

A in the drawings represents the base-plate of my improved metallic railroad-tie, which is cast with longitudinal side tlange, a, intermediate ribs, a', andtransverse pieces a2, which form seats for the arched bearing-plates B, as shown clearly in Fig. l. The bearing-plates B are transversely recessed at their top, so as to provide the proper space for the rails,which are supported on 'chairs O, that are cast integral with the base-plate A. The base of the rails is secured to the chairs C by means of clamps D, the ends of which are lapped over the base, as shown clearly in Fig. 2. The recess of the bearing-plate B,`instead of being at the center'of the same, is located about a quarter ot' an inch to one side ot' the center line of the bearing-plates, as shown clearly in Fig. 3, which has the advantage that by changing the position of one or both bearingplates in their seats ofthe base-plate A adifference otl from olie-quarter to one inch may be provided for in the distance ofthe rails from each other. By this simple means small inaccuracies of the rails and base-plates may be overcome, and thereby the exact width ot' track obtained, without any adjusting devices between the bearing-plates and the base-plate. The arched bearing-plates B are-provided at both sides of their central recess with inclined or daring portions b b, which extend from the sides ofthe recess up to and nea-r to the ends ot' the bearing-plates, so as to form therebyT at both sides ot' the rails inclined planes by which the wheels ot' the cars, if they be thrown out of the track, are returned toward the rails, so as to preventthe carst'roin leaving the ties and being thrown oft the embankment or bridge. The inclined or flaring portions ofthe bearing-plates serve thus as safety guards or devices by which the cars are retained close to the rails in case ot' derailment until the train comes to a stop, so that the upsetting ot` the cars and other accidents are avoided.

Having thus described my invention', I claim as new and desire to secure by Letters Patent- 1. The combination of' the base-plate A, having seats or sockets formed of the ribs au. a2 and chairs C, both cast integral with the base-plate, arched bearing-plates B, andclamps D, connecting rails and chairs, the bearing-plates having atop recess arrangedy slightly to one side ot' the center line ot' the arched plate, substantially as and for the purpose set forth.

2. The combination of the base-plate having seats or sockets for the bearing-plates and chairs for the rails, both cast integral with the base-plate, with arched bearing-plates, having top recesses for the rails and inclined safety-plates at both sides of the rail, and with I 1n testimony that 1 claim the foregoing as my invention l have signed my name in pres- 1o ence of two subscribing witnesses.

JOSEPH, CLARK.
